Development of Feeding Cues During Infancy and Toddlerhood.

ABSTRACT: To enhance responsive feeding, this study aimed to characterize the development of feeding cues during infancy and toddlerhood.A secondary analysis was performed on a dataset of first-time, low-income African American mother-infant pairs assessed at infant age 3, 6, 9, 12, and 18 months. A subsample with the 15 highest, middle, and lowest infant body mass index (BMI) Z-scores at 18 months was selected (n = 45). Using video-recorded home feedings, early, active, and late receptiveness and fullness cues were assessed using the Responsiveness to Child Feeding Cues Scale at each time point. Descriptive statistics were used to characterize development.Early receptiveness cues were relatively rare over time, whereas active receptiveness cues were much more common. However, there were changes over time. For example, settling into the feeding decreased from ~50% at 3 and 6 months to 4.8% by 18 months, whereas postural attention and reaching for food increased after 6 months. In the first 6 months, falling asleep and decreasing muscle tone and activity level were the most common early fullness cues. Thereafter, taking interest in surroundings was most prevalent. Active fullness cues became increasingly diverse after 6 months, led by more assertive cues such as pushing or pulling away and communicating "no" verbally or nonverbally.These findings provide an empirical description of waxing and waning in feeding cues and indicate increasing intentionality of cues over the first 18 months of life. Knowing common cues across development may aid clinicians in enhancing parental feeding responsiveness, avoiding overfeeding, thereby decreasing risk of early childhood obesity.

Project description:Background/objectivePer- and polyfluoroalkyl substances (PFAS) have neurobehavioral toxicity in experimental studies. Evidence on associations between prenatal PFAS exposure and child's cognitive development is inconsistent partly due to differences in assessment time points and tools. We examined associations of prenatal maternal serum PFAS concentrations with child's cognitive development assessed at multiple time points in infancy and toddlerhood.MethodsWe included 140 mother-child pairs from MARBLES (Markers of Autism Risk in Babies - Learning Early Signs), a longitudinal cohort of children with a first degree relative who was diagnosed with autism spectrum disorder followed from birth. Study children's cognitive development was assessed at 6, 12, 24, and 36 months of age using the Mullen Scales of Early Learning (MSEL) which provides an overall Early Learning Composite (normative mean of 100 and SD of 15) and four subscales (i.e., fine motor, visual reception, receptive language, and expressive language abilities; normative mean of 50 and SD of 10). Nine PFAS were quantified in maternal serum collected during pregnancy. We examined associations of log 2-transformed prenatal maternal serum PFAS concentrations with the MSEL Composite and each of the subscale scores at each time point as well as longitudinal changes in the scores over the four time points. We also classified trajectories into low- and high-score groups and fit Poisson regression models to estimate associations expressed as relative risks (RR).ResultsAmong six PFAS detected in more than 60% of the samples, prenatal maternal serum perfluorooctanoate (PFOA) was inversely associated with child's Composite score at 24 months (β = -5.22, 95% CI: -8.27, -2.17) and 36 months of age (β = -5.18, 95% CI: -9.46, -0.91), while other five PFAS were not strongly associated with Composite score at any time points. When assessing longitudinal changes in the scores over the four time points, PFOA was associated with trajectories having a negative slope for Composite scores and all four subscales. When examining trajectories of the scores between low- and high-score groups, PFOA was associated with having lower and/or decreasing Composite scores (RR = 1.49, 95% CI: 1.09, 2.03).ConclusionsPrenatal PFOA appears to adversely affect child's cognitive development in toddlerhood in this study population. Because a large fraction of MARBLES children is at risk for atypical development, population-based studies are needed to confirm our findings.
